With Other objects of the invention are to provide the motors 5 in vertical position, as suggested in e aflying machine of the character described which dotted lines in Figure 2 of the drawings, said 25 will be comparatively simple in construction, motors constitute a support or landing gear for Strong. durable, fl cient and reliable in operation, the machine. With the motors 5 in this vertical compact and which may be manufactured at low position the machine may be caused to ascend cost. and descend vertically.

It will thus be seen that should the craft tilt from a horizontal plane while in flight, the fluid 25 will immediately flow by gravity into the lowermost ball 2| and expand same in a manner to increase the speed of that motor and bring the craft to a horizontal position.

It is believed that the many-advantages of a flying machine constructed in accordance with the present invention will be readily understood and although a preferred embodiment of said machine is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: A flying machine of the class described, comprising a fuselage, a plurality oi. motors mounted on said fuselage, propellers driven by said motors, common means for manually con-
